This disclosure relates to storing a secure application directory within a contactless smart card. The contactless smart card include secure memory area for storing software applications and may include a default application directory for listing the software applications stored within the contactless smart card to an external card reader. A second application directory is stored with an access key and a listing of a second set of software applications within the same contactless smart card. The second application directory includes improved application directory entries, where each application directory entry includes an application identifier, a starting memory block byte value, and a size byte value for each of the second set of software applications.

Secure application directory

Systems and techniques by which a single electronic device can implement a variety of customized control interfaces. The control interfaces can be tailored to specific operations performed the device which is controlled. In one aspect, computer-implemented methods for controlling a web-based application include providing, from a server, a web page that includes a web-based application and a uniform resource identifier specifying a control interface for the web-based application and transmitting the control interface specified by the uniform resource identifier to a client for use in controlling the one or more functions of the web-based application. The control interface is configured to permit a user to control one or more functions of the web-based application from a mobile device.

Implementing customized control interfaces

One embodiment of the present invention provides a system that identifies network switches along a path. During operation, the system receives an address of a source node and an address of a destination node. The system maintains a set of topology information for a network. The system further simulates a data packet originated at the source node and destined for the destination node. During the simulation, the system determines whether a current-hop node performs layer-3, layer-2, or sub-layer-2 switching. The system sends a query to the current-hop node over a separate control channel to determine the status of the current-hop node and discover a next-hop node. The system then receives a reply. The system determines the next-hop node based on the reply and sets the next-hop node as the current-hop node.
